How to make fluoroboric acid
WebThe Hammett acidity function, H 0, of 50.7% to 79.2% aqueous fluoroboric acid has been determined by 13 C NMR spectroscopy (the Δδ 0 method) with mesityl oxide as indicator. At all concentrations, the H 0 values are more negative than those of sulfuric or trifluoromethanesulfonic acid solutions, increasingly so at higher concentrations. The … WebBoron trifluoride reacts with water to give boric acid and fluoroboric acid. The reaction commences with the formation of the aquo adduct, H 2 O−BF 3, which then loses HF that gives fluoroboric acid with boron trifluoride. 4 BF 3 + 3 H 2 O → 3 HBF 4 + B(OH) 3.
